Tesla’s Battery strategy is in preparation for two of its most anticipated vehicles
Tesla has continued to attempt to improve its battery packs and cells despite being the industry leader in EV battery tech. Interestingly enough, the electric car company located in Silicon Valley has had some of the best vehicles in terms of EV range in the past ten years. While other car companies were struggling to equip their attempts at electric cars with 100 miles of usable range, Tesla was and has been pushing the envelope since the original Roadster in 2008.
But even though the company has facilitated several vehicles in its fleet to have over 300 miles of range, and one with over 400 miles, it hasn’t been enough to let Tesla’s battery engineers rest. Even though the Model S Long Range Plus configuration packs 402 miles of electric range, which is plenty for most drivers, Tesla has several cars in the works that pack considerably more range than that. These are also not your “run of the mill” EVs, either. They are the Tri-Motor Cybertruck and the next-gen Roadster.
Batteries are what drive an EV to be all that it can be. They are responsible for the range and the performance of the car, along with the motors and engineering of the chassis and body. However, battery tech is ultimately what decides if a vehicle is going to be a successful electric car or just another one to add to the list of underperforming automobiles.
The key to building a great electric car, like anything else, is starting at the foundation. When you want to make a great pizza, you start with great dough. When you want to make a great EV, you start with the battery cells.
The problem with batteries is that there are no two cells that are the same when the materials that are used within are concerned. Not only that, but sometimes the elements that make some batteries stable and help with energy density are controversial. This is the case with cobalt.
But before I go into a spiel about Tesla’s use of cobalt and how the company responsibly sources it, let’s stay on topic.
Tesla’s battery teams in Canada, led by Jeff Dahn at Dalhousie University, released a new paper this week that indicated an electrolyte solution could contribute to increased battery energy density, and could lead to an extended lifespan.
This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
A big thanks to our long-time supporters and new subscribers! Thank you.
The solution would be used to combat the effects of degradation, and would ultimately lead to a longer life span and increased energy density. Enter the Tri-Motor Cybertruck and Roadster.
Both of these cars have range ratings that are well above the Model S Long Range Plus variant. The Cybertruck’s Tri-Motor will have 500+ miles of range, and the Roadster will have 620 miles.
However, Tesla’s current cells are not capable of holding this amount of range. If the batteries are not capable of holding excessive amounts of energy density, they will not perform in the fashion that they were intended. Therefore, Tesla has to continue developing its cells to promote longer-range driving and a long lifespan.
Starting with the Cybertruck, which has an estimated range of “500+ miles,” according to Tesla’s website. Currently, Tesla does not have a battery pack released that is capable of that kind of range, so the batteries must improve. The Tri-Motor setup will certainly help with the towing capacity and acceleration. Still, the battery pack within the Cybertruck has to work efficiently to not only supply power to those motors, but it also has to maintain energy so it can keep range at a reasonable level.
With the Roadster, things are slightly different. This car will (more than likely) not be towing things or have excessive amounts of cargo in the back, so there isn’t as much involved with maintaining range through laborious work. However, it is one of the fastest cars ever made, and Elon Musk has said in the past that the range of the Roadster will be over 1,000 kilometers or 621 miles.
Ultimately, the development of Tesla’s cells has to continue to improve. Obviously, the battery packs for both of the vehicles that were talked about in this article will have battery packs that are larger than the 100 kWh packs that Tesla puts in the Performance variants of the Model S and Model X. But there is a chance that Tesla equips the Cybertruck and Roadster with smaller, more energy-dense batteries like the 2170 cells that are used in the Model 3 and Model Y.
Lucid’s reveal of the 517-mile range that their new EV, the Air, has, certainly must have lit a fire under the rear-ends of Tesla’s battery engineers. Tesla has had a reputation of being the EV company with the best range, and now that Lucid “technically” has the title for that, even though the car isn’t in production, Tesla will likely be gearing up for a takeback of that label.
Tesla’s battery strategy from here on out will be interesting considering other auto companies have proven they are capable of competing in terms of EV range. There is still the fact that Tesla is actually producing these cars on a massive scale and we know that the company’s cars can perform, we don’t know this about the other vehicles yet.

Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
